读下面的两个片段,再做练习。    

       ①那个家伙摆出一副非常刻薄的嘴脸,说道:“啊,是吗?哼,当然我也料到了你没有带零钱。我看像你这样的阔人是只会带大票子的。”     

       ②他微笑着接了过去,那种笑容是遍布满脸的,里面还有折纹,还有皱纹,还有螺旋纹,就像你往池塘里抛了一块砖那个样子;当他向那张钞票瞟了一眼的时候,这个笑容就马上牢牢地凝结起来了,变得毫无光彩,恰像你所看到的维苏威火山边上那些小块平地上凝固起来的波状的、满是蛆虫似的一片一片的熔岩一般。 

1.文中画“       ”线的句子的意思是    (    )   [ ]

     A.这是托德在恭维我,因为他认为我是个有钱人。  

     B.这句话是反话,托德在挖苦、讽刺我是个穷人,根本没有钱。 

2.语段②描写的是托德的笑容,分号前写的是托德          时的笑容,分号后写的是托德          时的笑容。

3.托德的笑容为什么凝结了起来?在你认为正确的答案后打“√”。   

     ①他从未见过这么大的钞票,已呆若木鸡,不知所措。(     )   

     ②他感到难堪、窘迫,更多的是对钱的贪恋之心使他忘记了继续笑下去。(    )

4.从语段①和②中可以看出作家运用了          手法,淋漓尽致地刻画了一个             的托德。

When is the right time to get kids involved in teamwork and what does it mean to be part of a team? There are many great ways to introduce kids to team building. Use team building games and activities to get kids to understand the meaning of being in a team.

Try to find some games that have kids work together on some kind of problem solving. Children naturally have a shorter attention span (一段时间) than adults so present it in a funny way. Create a reward system for teams that are able to work together in order to reach a common goal. When they solve the problem and receive a reward, it gives them initiative to keep working hard and cooperating with others. The best games are those that require direct communication between team members.

Organize a game of 20 questions for the kids to play while building a team. Draw up a series of cards with different questions on each. Have each child select a card and then ask another question on it casually. It’s a great way for the kids to share and discover common interests. Kids need to be entertained and social when in a large group. This will lighten the mood greatly and help the quieter team members to come out of their shells.

Have the kids sit in a circle or around a table and share their favorite things. Start with something like movies or books and move on to anything from toys to animals. Sharing interests creates discussion. When you share interests with someone, it is easier to relate to them. Kids finally want to be friends with most other kids. Encouraging them to get along socially is always positive. By sharing interests they can form valuable bonds that will serve them as both individuals and as a team.
